System Price Format

T4 publishes prices in two formats: Decimal (default) and Real. The setting controls only decimal placement on all prices, including chart data and API responses.

If you expect ES to look like 5954.75 instead of 595475, choose Real.

Formats

Format Description Example (ES)
Real Human-readable decimal placement used by most trading UIs. 
5954.75
Decimal (default) Raw exchange representation, without UI-friendly decimal placement. 
595475

Where it applies

All price fields in API and REST responses

Streaming market data and historical/chart data

Set format during login

Streaming API (gRPC)

var loginRequest = new T4Proto.V1.Auth.LoginRequest {
Firm = demoConfig.Firm,
Username = demoConfig.UserName,
Password = demoConfig.Password,
AppName = demoConfig.AppName,
AppLicense = demoConfig.AppLicense,
PriceFormat = T4Proto.V1.Common.PriceFormat.Real
};

REST

Option 1 — Use bearer token from Streaming API\ If you authenticate via Streaming and reuse that bearer token, the price format is already set. No additional REST setup is required.

Option 2 — /login endpoint\ Specify priceFormat in the request body: 

{
"firm": "CTSDev",
"userName": "user",
"password": "*****",
"appName": "TradeBook",
"appLicense": "F18CC97E-42D1-478A-8CE9-0A850B5C47A7",
"priceFormat": "Real"
}
